It's horrible but it eases I promise I had a patch where I couldn't keep water down. Just keep hydrated Hun hospitals can't do much :( except anti nausea :)
I was like that for 6 months of my pregnancy lol its hard but its normal ask ur doctor for zofran it works
I don't think theres a limit to how many times you can throw up. Try to stay hydrated best you can. Have you anything to help, medically or naturally? If you don't mind meds see if you can get prescribed something to help. Natural things that workes for me were mainly hard peppermints. Other things that helped some. Toast with a lil butter, crackers and ginger ale (only for a short while until they started to make me sicker), bananas, and pineapple. Oh they also have these things called pregnancy pops, I never tried em but I heard they help sometimes too. I saw em at babiesRus.
It can be id suggest just making shore you are keeping hydrated and keeping enough food down that your not loosing weight. If you can do this you should be fine till you'r next appointment
